How do I match a drive to my conveyor?
Size by required belt pull and speed: calculate motor power from tonnage, lift and friction, then select gear ratio and coupling to handle start-up torque.

Disc Brake
盘式制动器
Conveyor brakes for inclined belts that must hold the load when the drive stops, sized to the actual holding torque rather than the motor rating.

Usage
Usage
Disc Brake — a spring-applied, hydraulically or pneumatically released caliper clamped on the pulley shaft. It holds the conveyor stationary when stopped and arrests it fast in an emergency; critical on inclined conveyors where a stopped belt would otherwise run backwards under load and cause a catastrophic rollback. (Distinct from a backstop: a brake is actively controllable and can be released; a backstop only blocks reverse rotation.)

Technical overview
Drive components deliver power from the motor to the pulley. HBXM supplies gearmotors, fluid and grid couplings, and brake units selected to match belt tension, torque and starting load for reliable starts under full burden.
Why use a fluid coupling?
It soft-starts the motor under heavy load, limits inrush current and protects the gearbox from shock during acceleration.
When is a holding brake required?
On inclined conveyors a brake holds the loaded belt stationary when stopped, preventing rollback and protecting the coupling and structure.
Can HBXM supply a complete drive package?
Yes. We bundle motor, gearbox, coupling and brake with the drive pulley so the power train is matched and tested as one set.
What is a torque limiter on a conveyor?
A torque limiter sits between the gearbox and the drive pulley and slips or disengages when torque spikes, protecting the gearbox, shaft and belt from jams and overload.
How do I choose a conveyor belt motor?
Size the conveyor belt motor from belt speed, capacity, lift, friction and starting load, then add margin for cold starts and heavy bulk. We match motor and gearbox to your duty cycle.
